You don't have to select one compiler.  We've got many production compilers installed (Intel, PGI, Cray, numerous versions of  GCC),  a number of official  `friendly' versions maintained, and dozens of unofficial builds (e.g. clang).  

Given the fast flux of the LLVM interfaces, getting hung-up on the lowest common denominator for a C++ compiler seems weird to me.
